However, as crucial as the law remains as the revelation of God’s moral will, it is different from the revelation of God’s saving will. We are called to love God and neighbor, but that is not the gospel. Christ need not have died on a cross for us to know that we should be better people. It is not that moral exhortations are wrong, but they do not have any power to bring about the kind of world that they command. These exhortations and directions may be good. If they come from the Word of God, they are in fact perfect. But they are not the gospel.
